Specification of Letters Patent.

To'aZZ whom it may concern."

Be it known that I, WILLIAM H. FonsY'rII, a citizen of the United States, and a resident of Chicago, Cook county, 1llinois, have invented certain new and useful Improvements in Curtain-Rollers, of which the following is a specification.

My invention relates to curtain rollers and has particular reference toa form of roller which is built up of a plurality of sections, and may thus be made of any desired length. In the construction of the curtain roller, two features are of greatdesirability; first, that the roller should be sufliciently rigid in order to prevent any danger of bending, and second, that it should be readily possible to vary the length of the roller according to any particular requirements. These results I accomplish by using a plurality of metallic sections which are joined end to end by meansof using a plurality of inner sections which closely fit Within the outer sections. Each of the inner sections is placed so that approximately one-half of its length is within one outer sect-ion and the remaining portion of its length is within the next adjacent outer section. By using such a construction it will be apparent that the roller may be made of any desired length, slight adjustments being effected by sliding one of the outer sections on its telescoping inner section. Not only can a roller be made of any desired length in this manner, but the presence of-the inner sections throughout the entire length of the roller, serves to reinforce the same, and the roller becomes rigid and resists bending action. The outer sections of -the roller are constructed with inwardly projecting ribs which are designed to receive shaped longitudinally split metal. The inwardly pro ecting rib just mentioned, is formed on one side of this longitudinal slit, whereas the opposing edge, of the section is formed into a lip which incloses the free edge of the rib. This lip forms a rounded edge on the outer portion of the rib and thus proved curtain roller.

tain edge held by the wire within the rib.

The'base of this inclosing lip is slightly depressed in order to form an engagingsun face for one edge of the longitudinally split inner section which fits within the outer sec: tion and whose opposite edge has its bearing against the base of the'inwardly projecting rib above mentioned. The two end sections of each curtain roller are provided respectively with a cap with which is inte grally formed a pawl controlled mandrel and a piece of metal which is suitably placed to similarly form a cap and a projecting pintle. These and other advantages of my invention will be more apparent by reference to the accompanying drawings which show'a preferred embodiment of my im provements and in which:

Figure 1 is a side elevation of my im' Fig. 2 is an enlarged fragmentary vertical sectional view through the roller shown in Fig. 1. Fig. 3 is an enlarged transverse section on the line 3 -3 of Fig. 1. Fig. 4 is an end elevation of the curtain roller showing the pawl controlled- Fig. 5 is an end ele- ,p

mandrel in position. vationnof the opposite end of the curtain roller showing the pintle in position. Fig. i

6 isa fragmentary verticalsection on the line 66 of Fig. 5.

In one of the outer sections 10 is placed '1 the inner connecting section 11 which extends into the outer section for a distance corresponding to about half of its length. On the projecting end of the inner sect-ion 11 is then placed a second section 10 which is forced into position so that the edge of its end abuts against the edge of'the adjacent section 10 first mentioned. This operation is continued until the curtain roller is built up to approximately the desired length.

Each of the outer sections 10 is construct ed with an inwardly projecting rib 12 on one side, the opposing edge being bent into the form of a lip 13 which incloses the out edge of the rib 12 and thus protects the curtain from the wear which would be caused by contact with a rough or sharpened edge. By thus inclosing the out edge of the rib 12, a depression 14 is formed at the base of the inclosing lip 13, and on its inner portion forms an engaging surface for the edge 15 of the inner section 11. This inner section 11, when removed from engagement with the outer section 10, by the spring quality of the metal of which it is constructed, normally assumes a diameter which is greater than the diameter of the outer section 10. In this way when the inner section is placed within the outer section, a tight fitis obtained. As most clearly shown in Fig. 3, the edge 16 of the inner section 11 engages the angle which is formed at the base of the inwardly extending rib 12.

In building up one of the curtain rollers, the first section which I use is preferably an end section, as for example, the one shown at the left in Fig. 1. Fitting into the outer end of this section, is the cap member 17 which is formed with the pintle 18 integral therewith. The edge 19 of this cap abuts against the lip 20 which is formed around the circumference of the outer section 10 and the edge 21 of the section is rolled inwardly over the cap member 17, thus holding it securely in position.

When the curtain roller has been built up to a length slightly less than that which is finally desired, the end section 22 is placed in position, being moved along its corresponding inner connector section 11 until the exact length of the roller which is desired is obtained. In order to fasten the sections securely in position, a slight amount of solder may be used between the inner and outer sections, although I generally find this is unnecessary. The section 22 has a cap member 23 held in its end in a manner similar to that in which the cap member 17 is held in the end section 10. Formed integrally with the cap member 23, is the pawl controlled mandrel 24:, of well known construction, the pintle 23 and mandrel 24: acting as supports for the roller.

It will be apparent that many changes may be made inthe detailed construction of the parts which I have described without depart-ing from the spirit of my invention.

What I claim is:

1. In a reinforced metal curtain-roller, the combination of a plurality of axiallydisposed outer hollow sheet-metal sections arranged end to end having alined grooves for the accommodation of the attachment edge of a curtain, and a plurality of inner hollow sheet-metal sections also arranged end to end inthe outer sections and extended substantially the full length of said roller, each of said inner sections internally tele scoping with at least a pair of said outer sections, substantially as described.

2; In a reinforced metal curtain-roller, the combination of a plurality of axially-disposed outer hollow sheet-metal sections arranged end to end having inwardly-projecting hollow ribs affording an external groove arranged longitudinally of the roller for the accommodation of the attachment edge of a curtain, and a plurality of inner hollow sheet metal sections also arranged end to end in the outer sections, formed to accommodate the ribs of said outer sections, and extended substantially the length of said roller, each of said inner sections internally telescoping with at least a pair of said outer sections, substantially as described.
